Application filed September 23, 1910.

T0 (/ZZ 107mm it may concern .ie it known that l, SATiICEL A. ITnmron,of Edgewater Park, in the State of New Jet have invented a certain newand us ful lii'ipi'ovenieiit in Duplicating-daclnncs, whereof thefollowing is a specification, reference beinghadv to the accompanyingdrawings.

My invention relates to machines adapted for printing and isparticularly applicable to a machine constructed in accordance with myinvention described in application Serial tiled September 28, 1910, forLet the Patent ot' the United States.

Such a machine in its preferred form includes a rotary printing couplecomprising a type carrying drum and a platen, the latter being movableaway from said drum to render the couple inoperative; paper feedingmechanisn i comprising two rollers one of which is movable away from theother to render them inoperative, and a cam which is rotatablyadjustable with respect to the drum to render said feeding mechanismoperative and inoperative in definite relation to the location of theprinting form on the drum. Said platen is provided with. a detent whichnormally detains it in operative relation with the drum, and a springwhich tends to shift the platen into inoperative position when saiddetent is released. The term of my invention herein shown as ap plied tosuch a machine as above mentioned includes an. electrically operativereleasing mechanism for said detcnt, controlled by two electricswitches, one carried by the feeding mechanism and both operated by saidcam, so that, said releasing mechanism and switches being included in anelectric circuit with a source of current, said relcasing mechanism isoperated and the printing couple rendered inoperative when both of saidswitches closed, such ciosurc'being consequent upon the omission of asheet of paper when it should be between said feed rollers.

My invention includes the various novel features of construction andarrangement hereinafter more definitely specified.

In said figures, l is the frame of the duplicating machine comprisingthe rotary printing couple consisting of the drum 2 which is fixed onthe rotary shaft. 3, and the platen at which rotates loosely on thenormally stationary shaft Said drum 2 is conveniently provided with thestationary hooks 7 and the oscillatory hooks 8 to detachably engage theflexible chase 5) constructed to hold movah c set type 10 as in theapplication aforesaid. but may other wise adapted to hold printing=forms of different sizes. Said 'wleu {has means to shift its axis towardand away from said drum 2 includingthe eccentrics 11 and 12 on its shaft5 and the npression lever Ll to turn said shalt. Said platen nonnallyretained in coo s-rative -elation with said drum as shown in 'Fi U andVl, by the o detent including the pli g'cr l3 which engages the socketN3 n ti 2 flange 17 of said lever 14. Said \lclent is carried by thereleasing lever 18 which is tulcrumcd in the stud 19 on the ironi 1 andha at site end the manually operative t ton plunger 20, which ar ss bythe spring L1. The s, ring circles said platen shall 51 a thereto at oneend. beinghell. end in said trame 1. tends to e; in the direction of theanon II, when re eased; so that w 15 is withdrawn by inwa d iii-w men;c'

ing tothrust it outward from; the electronet 24 shown in Figs. V a lfidVIII havingthe oscillatory armature 25 pivoted at 26 in the box 27 andhaving the spring 28 tendmagnet to the position shownin said figure.When insaid posit on, said armature rests against the stop wire 29 andupholds-the latch-lever 80 which is pivoted at 81 in said box 27 and hasthe recess 32 for the stop H pin 34 on the tripping lever 35 soas'tonormally hold the latter in the position shown against the stress of itsspring 36 which en circles the pivot 37 of said lever 35 and tends tothrow the latter and the releasing lever 18 inward when said armature isdrawn toward the electro-magnet far enough to release said catch leverand permit the lat ter to fall and free the pin 34 of the trippinglever. It will. be seen from Fig.

:VIII that this tripping lever 35 is a bell-crank having a substantiallyhorizonthe feed roller 38 journaled in said frame 14.

talarm projecting outwardly from the hinge pin 37 and passing through anopening in the frame plate 1, so that its extreme portionis exposed andconstitutes a finger piece to return this lever or hinged member 35 andthe latch-lever 30 to normalosition. This return of the latch leyers 30is caused by the pins 34 engaging the shoulder provided by the forwardwall of the recess 52 in the latch lever.v "When the pin engages thisshoulder it rocks the latch lever about its own pivot 81 and therebyraises its rear end to allow the armature to spring beneath it. As'hereinafter described, said automatic releasing mechanism is arranged tobe electrically operatedY-in accordance with the position of thepaper'feeding mechanism, which as shownin Fig. VI includes above thetable 89 but'idly rotary with its axis stationary. Said feedroller 38isopposed by and driven by the pressure-of the feed roller 40 below saidtable 89 having rubber faces to engage the cut sheets of 3 paper 42.Said roller 40'is raised to oooperative relation with said roller 38 bythe rock shaft-'43 having-the lever arms 45, in

which saidshaft is journaled, and thes'pring ld tending to'turn saidshaft the direc- 1 tion of the arrows shown in Eigs..1VIandIl,;.oneendof said spring ,46 beingconnectf *held inframe l'as indicatedin dotted lines ed to said shaftg43 and the othenendbein'g {in-Fig; IISaid arms 45 also carry the cross bar 47 having the paper stop fingers48in registr-y openings in the, guide plate '49 andftable so that whensaid arms do are oss-nee lowered each paper sheet 2 may be thrustagainst said fingers to insure its proper angular relation with themachine before being gripped by the upward movement of said roller 40against the roller 38. Said stop fingers 48 being raised when the papersheets 42 are thus gripped, they are fed into the machine by saidrollers; said roller 40 being positively rotated by its gear 52 which isengaged by the gear 54 which turns loosely on said shaft 43 and isdriven by the platen gear 55, which engages the gear 56 on'the drum 2.Said shaft43 is turned against the pressure of said spring 46 to I lowersaid roller 40 and stop f ngers 48 by the lever arm 58 on said shaft 43having the in the framel and carrying exterior thereto the frictionroller (33 in position to be enof the drum shaft handle 67 shown in Fig.

I. However, as'indicated in Fig. VI said platen gear 55 is engaged bythe gear 68 on the shaft 69 which extends through the frame 1 as shownin Fig. I. and is provided with the belt wheel 71 connected by thedriving belt 72 with the belt Wheel 78 on the stud shaft 59 extendingthrough the-slot 6O counter shaft 74 of the electric motor 75'.

As indicated in Fig. I said motor 7 5 has the conductors 76 leading tothe plu'g'77 in the socket 7 8 on thepanel 79 supported by the. stand 80and having the conductors 81 lead.

ing to the service plug 82,50 that as indicated in Fig. IX, said motormay be included. in circuit with the rhe'ostat 83 and. the sw'itch 84,and when the latter isclosed. as indicated in Eig. IX the speed of themotor and consequent speed of the machine may be adjustably determinedby manipulation of the handle 85 on said rheostat 83.

.- As shown in-Figs. III and IV said switch 84 has the push buttonsfi-Yand 88 t0. respec-1 tively-close and open it a'nd as indicated in' vFigrlX it not only controls the circuit to said motor" 75 butcontemporaneo uslv' controls the stop mechanism circuit 89 including thebattery 90 connected by the conductor 91- with thereleasingmagnet coils24. The

conductor 93 connects said coils 24 with the switch terminal 94 which.as indicated in Figs. II and V is a flat spring mounted on theinsulating block 95 in the frame 1 andhaving the screw 96 by which itmay be adjustably set' away from said block; said screw 96 having thejam nut 97 to secure it in adjusted position as shown in Fig. II.

"itch member '94 is opposed by the resnitch member 98 which is secured irelation with the shaftby the ."n, screw 99 shown in. Fig. V, so thatsaid 5 switch member 98 oscillated with the paper feeding illQCllll ism,above cescrioed; the arrangement being such that when the cam 65, turnsthe arm 58 into inoperative position, said sr-xitch is opened, and whensaid cam permits said arm to return to the ppw'ition. oi the feed rollerl0 said. switch is c wed, unless a sheet of paper 42 is n nucd betweensaid rollers 38 and 40, llltilCklllCCl in Fig. IX.

As shown such mechanism inaced ink transferroller Mich has the ear 112 engaging the a drum and is normally pretheposition shown in Fig. VI to l; to said sheet 104- or form. 10.mechanism which is supported 3 113, :nljustable toward and drum 2, alsoincludes the y 26 and 117 having means to turn them and intermittently5119M a donuite; adjustal'rly \idriable amount the rubluu- 1' 100,pressed by of ink 1120 upon said transfer roller 110. The supply of saidink 120 is upheld by and between said rollers 116 and 117 and a pair ofinl; ates 1551 which are pressed between said r0 lers by the spring arms123 on the cross heads 12% which are adjustable toward and away fromeach other and are secured in adjusted position by the thumb nuts 125 onthe bolts 126.

The mechanism above described may be used as follows: The type 1.0 beingset in the desired form in the flexible chase 9, said chase is attachedto the drum 2 and covered with the ink transfer sheet 104: as shown inFig. VI. The guides 127 oil-the paper chute 128 shown in Fig. I beingset to direct cut sheets of paper 422 of the desired size in the desiredrelation to the width oil type form; the cam is rotatably adjusted onsaid drum so that when each sheet 42 is presented against the stop'lii-igers l8 itwill be gripped. at the proper instant to be drawnbetween said drum and the platen in such relation as to locate-theprinted impression thereon in the desired position with respect to thelength oi said sheet.

The inking system described acts to coat the transferrollcr with a filmof ink suliicient to replace upon the transfer sheet 10%. or type id ateach impression the amount of ink which is removed thcretrom'by eachimpression of the type form. A sheet of paper being then inserted overthe table 39 beneath the guide plate 49 against the stop fingers 48,and, said drum 2 being turned in the direction of the arrowmarkedthereon in Fig. VI, said feed roller grips said 'shcct against the feedroller 38 to draw it between said drum 2 and platen 4, print it, anddischarge it over the rollers 130, on the shaft 151 which is rotated byits gear 13-32 engaging the gear 68 on the shaft (3.). Said rollers havecorrugated soft rubber faces which en 'age said sheets and direct thcnragainst the inclined guide strips shown in Fig. Vi, so that said sheetsfall into the rack 135 as shown in Fig. I,

i-ilthough the operation of the entire machine as above described maybeinitiated, regulated and terminated by manipulation of the electriccont-rolling mechanism for the motor shown in Fig. l; the operator mayat any instant during such operation press the button 20 to operate thelever 18 and thus render the platen 4 inoperative and terminate theprinting operation without stopping the machine.

Although l find it convenient to'providc the machine with the electricmotor and controlling mechanism connected therewith as indicated in l irsjl and lit, it is to he understood that said motor and its circuit may,be entirely omitted and the macl'iine oper above described.
